Highest power density of any tantalum capacitor technology.
TDE Hybrid Capacitors utilize a sintered tantalum anode and ruthenium oxide coated cathode operating in aqueous with additive electrolyte. The components are hermetically sealed in a welded tantalum case with a glass-to-metal anode terminal seal.
The TDE series capacitors combine high capacitance and low ESR in a fully hermetic tantalum package for high reliability Defense and Aerospace applications where weight and volume are at a premium. Especially suited for high power pulse applications, with excellent heat transfer and low inductance.
1.4 x 1.4 square base
Heights range from 0.312 – 0.75″
Voltages range from 6V-125V
Cap values range from 1,100uF – 250,000uF
Temperature range of -55°C to 125°C
Standard tolerance ±20% (±10% available upon request)
TDE Series capacitors are rated for >2,000 hours at 85?C and rated voltage or 125?C at de-rated voltage. The effective life of a capacitor in a given application is based on the specific operating voltage and average temperature.
TDE Series Capacitors have an unlimited Shelf life.
Attachment / Mounting by leads only is discouraged in applications exposed to mechanical shock or vibration. Always ensure capacitor is firmly secured to PWB, by either mounting studs, epoxy staking or both (preferred for vibration environments)
Provide adequate care to protect the glass to metal seal (GTMS)
Avoid forces on the positive terminal, lateral, axial or torque.
Avoid mechanical shock to the positive terminal.
Secure the part to PWB before soldering.
Mounting with studs
#2-56 CDA-752 studs are available as a standard option.
Use spacers (provided) to fill the gap between PWB and leaded surface of capacitor.
Tighten Studs to 30-40 in-oz.
Secure nuts (provided) with red Loctite. Do not use lock washers.
Potting / Epoxy Staking
We advise epoxy staking capacitor to PWB even when using studs, for maximum vibration tolerance.
In some applications it may be advisable to pot the cavity between the PWB and leaded surface.
Highest shock/vibration applications may require the capacitor to be fully potted.
Soldering
Rim of Capacitor is intended to mate directly to PWB. Advise using “no-clean” flux.
Utilize ANSI J-STD 001 Standard Through hole Soldering methods
Lead Trimming
Provide adequate care if leads must be trimmed.
Trimming the positive terminal is not recommended.
Lead lengths available in 1/32″ increments from 0.125″ when measured from the rim of the capacitor.
